To all whom it may concern:

Be it known that we, TILLMANN l?. Fmr.- GENSCHMIDT and Louis V. PRINZLER, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Cooling-Coil Frotectors, of which the following is a specification.

This invention relates to coils used in boxes for cooling beer, water and other liquids for drinking purposes, wherein the temperature of the liquid which is drawn through a pipe arranged in a coil in the box, is cooled by surrounding the coil with broken ice.

Damage is done to the coil which is generally of lead, by the mashing together of the walls, particularly of the top convolution, due to haste and carelessness in depositing and packing the ice in the box. Often, also, the boX is filled too full and the ice is compressed and hammered downto get the lid closed, and the iiattening together of the walls of the coil retards the flow through it and frequently cuts it off altogether.

rlhe object of this invention is to provide a guard or shield for the upper end of the coil which receives the impact in icing the boX.

We accomplish the object of the invention by the device illustrated in the accompany-y ing drawing, in which- Figure 1, is a vertical cross section of an ice-box containing a spiral coil'mmprovided with our improved guard. Fig. 2 is a top plan view of the coil and guard on a much larger scale than is shown in Fig. 1. Fig. 3 is a side elevation of the upper end of the coil with guard attached as in Fig. 2, and Fig. et is a section on the line i-Jl of Fig. 2.

Like characters of reference indicate like parts throughout the several views of the drawing. i

Referring to Fig. l, 5 is the ice-box `of any suitable size, shape and construction within which is located a coil (i, of spirally wound pipe-usually lead pipe-through which a liquid to be cooled passes from thelower member 7 and is drawn off through an upper member 8 and faucet 9. A stand-pipe.I

10 keeps the water from the melted ice-pack above the highest coil. Broken ice is introduced into the boX through its top which is opened by removing the lid 11.

The guard 12 is a cast annulus, preferably of brass on account of the hard and noncorrosive qualities of that metal. It is formed with an underside channel of such a depth as will receive all of the top convolution and approximately half of the second one of the series of convolutions in the complete coil. The walls of the channel will be of greatest thickness on top where the greatest impacts and coil-flattening pressures will be delivered, and the outer surface will preferably taper upwardly to a central line forming a ridge which will tend to separate the broken ice when the latter` is pressed against it and thereby reduce the force of the blows which flatten the coil when the ice is pounded downto get the lid on the box.

The shape of the guard and channel conforms to that of the spiral convolutions of the lead coil so the guard will lie firmly against the top one, and to keep the guard from being pounded loose we solder its lower edge at 13 to the second convolution as shown in Fig. 4. I

While we have described our invention with more or less minuteness as regards details of construction and arrangement, we do not desire to be limited thereto unduly or any more lthan is pointed out in the claims. On the contrary, we contemplate all proper changes in form, construction and arrangement as circumstances may suggest or necessity render expedient.

We claiml. In an ice-box having a pipe formed in a spiral coil through which a liquid is passed to be cooled, a guard supported entirely by the coil, said guard being in the form of an annulus having an underside channel which receives the top convolution with a close fit against its top by conforming to the spiral shape of said convolution, and receives part of theneXt lower convolution and is soldered to the latter.

In an ice-box having a pipe formed in a spiral coil through which a liquid is passed to be cooled, a guard supported entirely by the coil, said guard being in the form of an annulus having an underside channel which receives the -top convolution with a close fit against its top, and receives part of the one below andis soldered to the latter, the ehan diana, this 14th day of September, A.
